The new Active Route always disappears and I try to recreate it and it disappears again.
One possibility is that you have the space-bar set to drop a wpt at the boats position. This used to be standard behavior some time ago. If this is a problem, shut down OpenCPN. Open the file opencpn.ini, find the line:
SpaceDropMark=1 and change it to SpaceDropMark=0
Save and restart O.
So that the names show up beside each waypoint as it is placed? There is not a very easy way, but one at least much easier then you do now.
Now you should have all waypoint names visible.
The GUID box is not useful for anything but knowing the GUID. Knowing the GUID is good to be able to find a specific object in OpenCPN's GPX data when processed in a text editor. Doing things with OpenCPN's GPX data in a text editor is something you normally don't do, but when you do, you are most happy that you know the GUID of a certain object.
Question: Layers is a good feature, however I need a tool to create a layer with many waypoints (say 200 waypoints in Fiji). I'd like create a layer of all visible waypoints in a chart area that I have zoomed into. After creating the layer, I'd like to delete them from the waypoints list with a single command.
Answer: Using the Route & Mark Manager
- Activate the route first. Then you can activate a specific waypoint within it.
<CODE> <rte>
<name>test2edit</name>
<extensions>
[DATA}
</extensions>
<rtept lat="57.679627692" lon="11.796954074">
[ROUTE DATA]
</rtept>
<rtept lat="57.679627692" lon="11.796954074">
[ROUTE DATA]
</rtept>
<rte> </CODE>
Three ways to synchronize:
The navobj.xml file resides in the same folder as the opencpn.ini settings file, under the OpenCPN User folder. For windows this is usually “C:\programdata\opencpn\”. The navobject.xml file is in in fact a .gpx file containing all waypoints/routes/tracks. See Navigation Data Backup for more information.
Make a script or batch file to copy to navobject.xml file. Make an icon for the batch file on your desktop. Examples: Make an icon for the batch file on your desktop.
Copy-Routes-AB.bat
Copy \\ComputerA-name\C:\ProgramData\opencpn\navobj.xml \\ComputerB-name\C:\ProgramData\opencpn\navobj.xml
Copy-Routes-BA.bat
Copy \\ComputerB-name\C:\ProgramData\opencpn\navobj.xml \\ComputerA-name\C:\ProgramData\opencpn\navobj.xml

If you did delete the original [route, wpt, track], you may still have an automatic backup in an older navobj.xml.[1-5] file. Don't restart Opencpn again, until you retrieve the data you want. See Navigation Data Backup for more information.
This problem has been traced to shutdown management. Please see Tracker FS#2245 and OpenCPN and Linux powerup/down management For Windows and MAC users it is suggested that it is best to shutdown OpenCPN first, then shutdown the Computer.
Question: How to split a long route into shorter segments with each segment having its own start and end waypoint? When the split function is used, I get a new route name with an _B suffix, but it's still physically “connected” to the original route (now with a _A suffix) with a segment line connecting the two. I want to end up with two distinct routes that are not connected. How do I do that? Answer: The point where you did split the route exists now twice as start of one and end of the other route. Just hide one of the two routes and move the waypoint you are interested in as you like. Or insert additional waypoints and delete the first one.
Deleted all routes in the Route & Mark Manager. Found a gpx Route File folder under documents on my computer. Importing all gpx routes into Route & Mark Manager from Route folder by highlighting all the routes. Now multiple routes with the same name show. How can I correct this. Importing a route at a time is tedious.
I had previously exported all visible routes and had that file in my GPX Route folder. What happened: I imported single listed routes by highlighting all the files in my GPX Route folder. However I didn't notice the gpx file which had a group of routes contained in it. Once I removed the gpx file with a group of files, the import gpx worked as anticipated.
There are so many GPS models that the answer is a bit complicated. A lot depends on which GPS model you have. OpenCPN can communicate with many GPS receivers via a serial connection. Some GPS receivers have a serial connector that can be wired to a DB-9 serial connector. Newer ones have a USB port that will appear like a serial connection to your computer. Still newer ones appear to your computer like an external drive.
If your GPS receiver shows up as a serial connection on your computer chances are you can upload routes and waypoints directly to it from within OpenCPN. The GPS and OpenCPN have to be set to the same communication protocol. If you normally have them set to NMEA (for updating the OpenCPN chart display with position data from the GPS) you may need to change a Garmin GPS to the GRMN proprietary protocol to upload routes, waypoints, and tracks. If your GPS doesn't show up as a serial connection you may still be able to transfer routes and waypoints to it outside of OpenCPN. If the GPS appears as an external drive on your computer try this. Use OpenCPN to export your routes and waypoints to a GPX file (read the User Manual section on the Route & Mark Manager for more details). Then use your operating system to copy the GPX file from your hard drive to your GPS. If that doesn't work, try GPSBabel or EasyGPS for the transfer.
Depending on your GPS model and the way the route was created in OpenCPN you may wind up with a route on your GPS or just a list of waypoints. The route points may or may not appear as waypoints on the GPS.
There are also some good Cruiser Forum threads about Garmin
This depends on what “a bit ago” actually is - (if you have since started OpenCPN more than 5 times, every time did some change to the navigation objects and did not change the default settings for backups, you don't have it anymore) - If you do not have that backup anymore, you may still export the route as GPX file which you may later edit in a text editor and make a track again (But you already have lost some precision as during the conversion to route the points recorded in the original track are interpolated to limit their total number) - Later: your track seems to still be there as the yellow highlight it has seems to be visible, so you should be good just deleting the route.
When you export multiple routes or tracks in one operation they are all written to a single GPX file. That might be why you think only the last one is being exported. When you import the GPX file all the routes or tracks it contains will be restored. Note: In GE the Track looks strange, although all are marked visible, only one track at a time is shown.
No, not directly, they are in different formats. But you can convert them with the GPS Utility Program. Here's an older writeup Conversion of MaxSea Routes and Tracks Use an external tool to convert the proprietary Maxsea data to the open GPX format. Either the free C2GPXKML or shareware GPSUtility could help. Also if you have access to Maxsea, export all waypoints as Gpx and OpenCPN will read the gpx file. If different color waypoints is used, export them separately and and in a text editor change icon name to an icon used in OpenCPN.

Yes the NMEA WPL can be handled by OCPN but not the way you may want.
Detail: I make videos of the seabed and I would like to be able to drop a mark on the gps track when the camera hit the bottom and save this marker with the date and time. For now I can use the Man Over Board marker, but I don't think that's how it should be used.
Answer: You can drop waypoint marks using just the spacebar. No popup appears if you are normal zoom levels. OpenCPN records the mark and continues. Fishermen use this feature to mark locations of gear they drop. The User Manual describes this feature
The marks created using the spacebar are saved in a file called “navobj.xml”. Here is how one looks:
<wpt lat="37.838435000" lon="-122.656498333"> <time>2023-03-10T06:01:33Z</time> <sym>triangle</sym> <type>WPT</type> <extensions> <opencpn:guid>64d5ffff-1836-457e-a85f-ba7b5323ffff</opencpn:guid> <opencpn:viz_name>1</opencpn:viz_name> <opencpn:arrival_radius>0.050</opencpn:arrival_radius> <opencpn:waypoint_range_rings visible="false" number="0" step="1" units="0" colour="#FF0000" /> <opencpn:scale_min_max UseScale="false" ScaleMin="2147483646" ScaleMax="0" /> <opencpn:action>add</opencpn:action> </extensions> </wpt>
You can see the GPS coordinates at the moment the spacebar was pressed along with the computer UTC time. If the computer time is accurate, then so will the time recorded with the waypoint.
Are you connected to a GPS Signal? Have you zoomed in close enough?
